3pt sway bars

My 1720 has outer 3pt sway bars. Turnbuckles really. Unfortunately, I have a couple 3pt pieces that clamp over the 3pt arms right where these turnbuckle bolts attach to the 3pt arm. I would like to find some sway bars that attach to the hole closer in towards the tractor, 2" shorter. Any available?

I was just going to replace the one end of the turnbuckle with a shorter piece - but they turn out to be 14mm metric threads, left-handed, and this turns out to be difficult to find!

Guess I'll have to start fabricating if I can't find anything on the shelf. Could have been easy, but never is...
